Yes is the answer there was nothing worse than that. I've had a lot of stuff happen to me on courses but that was THEE single most annoying thing. I was a beginner who pretty much knew nothing, having to try and talk through a technique with someone older than me, more experienced than me, this was at a time where i was a quiet 15 yr old. It ws a pretty daunting prospect for me, Nowadays though my attitude has changed, Training has a different approach but that tye of situation will always annoy me. Hakama wearers in dojo's is fine, but at national and international coursesi still believe it should be for yudansha.
